Payload provides a variety of powerful [React Hooks](https://react.dev/reference/react-dom/hooks) that can be used within your own [Custom Components](../custom-components/overview), such as [Custom Fields](../fields/overview#custom-components). With them, you can interface with Payload itself to build just about any type of complex customization you can think of.

<Banner type="warning">
  **Reminder:**
  All Custom Components are [React Server Components](https://react.dev/reference/rsc/server-components) by default. Hooks, on the other hand, are only available in client-side environments. To use hooks, [ensure your component is a client component](../custom-components/overview#client-components).
</Banner>

## useField

The `useField` hook is used internally within all field components. It manages sending and receiving a field's state from its parent form. When you build a [Custom Field Component](../fields/overview#custom-components), you will be responsible for sending and receiving the field's `value` to and from the form yourself.

To do so, import the `useField` hook as follows:

```tsx
'use client'
import type { TextFieldClientComponent } from 'payload'
import { useField } from '@payloadcms/ui'

export const CustomTextField: TextFieldClientComponent = ({ path }) => {
  const { value, setValue } = useField({ path }) // highlight-line

  return (
    <div>
      <p>
        {path}
      </p>
      <input
        onChange={(e) => { setValue(e.target.value) }}
        value={value}
      />
    </div>
  )
}
```

The `useField` hook accepts the following arguments:

| Property          | Description                                                                                                                                                                                                                   |
| ----------------- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| `path`            | If you do not provide a `path`, `name` will be used instead. This is the path to the field in the form data.                                                                                                                  |
| `validate`        | A validation function executed client-side _before_ submitting the form to the server. Different than [Field-level Validation](../fields/overview#validation) which runs strictly on the server. |
| `disableFormData` | If `true`, the field will not be included in the form data when the form is submitted.                                                                                                                                         |
| `hasRows` | If `true`, the field will be treated as a field with rows. This is useful for fields like `array` and `blocks`.                                                                                                                                         |

The `useField` hook returns the following object:

```ts
type FieldType<T> = {
  errorMessage?: string
  errorPaths?: string[]
  filterOptions?: FilterOptionsResult
  formInitializing: boolean
  formProcessing: boolean
  formSubmitted: boolean
  initialValue?: T
  path: string
  permissions: FieldPermissions
  readOnly?: boolean
  rows?: Row[]
  schemaPath: string
  setValue: (val: unknown, disableModifyingForm?: boolean) => void
  showError: boolean
  valid?: boolean
  value: T
}
```

## useFormFields

There are times when a custom field component needs to have access to data from other fields, and you have a few options to do so. The `useFormFields` hook is a powerful and highly performant way to retrieve a form's field state, as well as to retrieve the `dispatchFields` method, which can be helpful for setting other fields' form states from anywhere within a form.

<Banner type="success">
  **This hook is great for retrieving only certain fields from form state** because it
  ensures that it will only cause a rerender when the items that you ask for change.
</Banner>

Thanks to the awesome package [`use-context-selector`](https://github.com/dai-shi/use-context-selector), you can retrieve a specific field's state easily. This is ideal because you can ensure you have an up-to-date field state, and your component will only re-render when _that field's state_ changes.

You can pass a Redux-like selector into the hook, which will ensure that you retrieve only the field that you want. The selector takes an argument with type of `[fields: Fields, dispatch: React.Dispatch<Action>]]`.

```tsx
'use client'
import { useFormFields } from '@payloadcms/ui'

const MyComponent: React.FC = () => {
  // Get only the `amount` field state, and only cause a rerender when that field changes
  const amount = useFormFields(([fields, dispatch]) => fields.amount)

  // Do the same thing as above, but to the `feePercentage` field
  const feePercentage = useFormFields(([fields, dispatch]) => fields.feePercentage)

  if (typeof amount?.value !== 'undefined' && typeof feePercentage?.value !== 'undefined') {
    return <span>The fee is ${(amount.value * feePercentage.value) / 100}</span>
  }
}
```

## useAllFormFields

**To retrieve more than one field**, you can use the `useAllFormFields` hook. Your component will re-render when _any_ field changes, so use this hook only if you absolutely need to. Unlike the `useFormFields` hook, this hook does not accept a "selector", and it always returns an array with type of `[fields: Fields, dispatch: React.Dispatch<Action>]]`.

You can do lots of powerful stuff by retrieving the full form state, like using built-in helper functions to reduce field state to values only, or to retrieve sibling data by path.

```tsx
'use client'
import { useAllFormFields } from '@payloadcms/ui'
import { reduceFieldsToValues, getSiblingData } from 'payload/shared'

const ExampleComponent: React.FC = () => {
  // the `fields` const will be equal to all fields' state,
  // and the `dispatchFields` method is usable to send field state up to the form
  const [fields, dispatchFields] = useAllFormFields();

  // Pass in fields, and indicate if you'd like to "unflatten" field data.
  // The result below will reflect the data stored in the form at the given time
  const formData = reduceFieldsToValues(fields, true);

  // Pass in field state and a path,
  // and you will be sent all sibling data of the path that you've specified
  const siblingData = getSiblingData(fields, 'someFieldName');

  return (
    // return some JSX here if necessary
  )
};
```

#### Updating other fields' values

If you are building a Custom Component, then you should use `setValue` which is returned from the `useField` hook to programmatically set your field's value. But if you're looking to update _another_ field's value, you can use `dispatchFields` returned from `useAllFormFields`.

You can send the following actions to the `dispatchFields` function.

| Action                 | Description                                                                |
| ---------------------- | -------------------------------------------------------------------------- |
| **`ADD_ROW`**          | Adds a row of data (useful in array / block field data)                    |
| **`DUPLICATE_ROW`**    | Duplicates a row of data (useful in array / block field data)              |
| **`MODIFY_CONDITION`** | Updates a field's conditional logic result (true / false)                  |
| **`MOVE_ROW`**         | Moves a row of data (useful in array / block field data)                   |
| **`REMOVE`**           | Removes a field from form state                                            |
| **`REMOVE_ROW`**       | Removes a row of data from form state (useful in array / block field data) |
| **`REPLACE_STATE`**    | Completely replaces form state                                             |
| **`UPDATE`**           | Update any property of a specific field's state                            |

## useForm

The `useForm` hook can be used to interact with the form itself, and sends back many methods that can be used to reactively fetch form state without causing rerenders within your components each time a field is changed. This is useful if you have action-based callbacks that your components fire, and need to interact with form state _based on a user action_.

<Banner type="warning">
  **Warning:**

  This hook is optimized to avoid causing rerenders when fields change, and as such, its `fields`
  property will be out of date. You should only leverage this hook if you need to perform actions
  against the form in response to your users' actions. Do not rely on its returned "fields" as being
  up-to-date. They will be removed from this hook's response in an upcoming version.

## useDocumentForm

The `useDocumentForm` hook works the same way as the [useForm](#useform) hook, but it always gives you access to the top-level `Form` of a document. This is useful if you need to access the document's `Form` context from within a child  `Form`.

An example where this could happen would be custom components within lexical blocks, as lexical blocks initialize their own child `Form`.

```tsx
'use client'

import { useDocumentForm } from '@payloadcms/ui'

const MyComponent: React.FC = () => {
  const { fields: parentDocumentFields } = useDocumentForm()

  return (
    <p>The document's Form has ${Object.keys(parentDocumentFields).length} fields</p>
  )
}
```

## useCollapsible

The `useCollapsible` hook allows you to control parent collapsibles:

| Property                  | Description                                                                                                   |
| ------------------------- | ------------------------------------------------------------------------------------------------------------- |
| **`isCollapsed`**         | State of the collapsible. `true` if open, `false` if collapsed.                                               |
| **`isVisible`**           | If nested, determine if the nearest collapsible is visible. `true` if no parent is closed, `false` otherwise. |
| **`toggle`**              | Toggles the state of the nearest collapsible.                                                                 |
| **`isWithinCollapsible`** | Determine when you are within another collapsible.                                                            |

**Example:**

```tsx
'use client'
import React from 'react'

import { useCollapsible } from '@payloadcms/ui'

const CustomComponent: React.FC = () => {
  const { isCollapsed, toggle } = useCollapsible()

  return (
    <div>
      <p className="field-type">I am {isCollapsed ? 'closed' : 'open'}</p>
      <button onClick={toggle} type="button">
        Toggle
      </button>
    </div>
  )
}
```

    <a href={`/admin/collections/posts?where[or][0][and][0][category][in][0]=[${id}]`}>
      View posts
    </a>
  )
}
```

## useListQuery

The `useListQuery` hook is used to subscribe to the data, current query, and other properties used within the List View. You can use this hook within any Custom Component rendered within the List View.

```tsx
'use client'
import { useListQuery } from '@payloadcms/ui'

const MyComponent: React.FC = () => {
  // highlight-start
  const { data, query } = useListQuery()
  // highlight-end

  // ...
}
```

The `useListQuery` hook returns an object with the following properties:

| Property          | Description                                                                                   |

| **`selectAll`**      | An enum value representing the selection range: `'allAvailable'`, `'allInPage'`, `'none'`, and `'some'`. The enum, `SelectAllStatus`, is exported for easier comparisons. |
| **`selected`**       | A map of document id keys and boolean values representing their selection status.                                                                                         |
| **`setSelection`**   | A function that toggles the selection status of a document row.                                                                                                           |
| **`toggleAll`**      | A function that toggles selection for all documents on the current page or selects all available documents when passed `true`.                                            |

const MyComponent: React.FC = () => {
  // highlight-start
  const { count, toggleAll, totalDocs } = useSelection()
  // highlight-end

  return (
    <>
      <span>Selected {count} out of {totalDocs} docs!</span>
      <button
        type="button"
        onClick={() => toggleAll(true)}
      >
        Toggle All Selections
      </button>
    </>
  )
}
```

## useLocale

In any Custom Component you can get the selected locale object with the `useLocale` hook. `useLocale` gives you the full locale object, consisting of a `label`, `rtl`(right-to-left) property, and then `code`. Here is a simple example:

```tsx
'use client'
import { useLocale } from '@payloadcms/ui'

const Greeting: React.FC = () => {
  // highlight-start
  const locale = useLocale()
  // highlight-end

  const trans = {
    en: 'Hello',
    es: 'Hola',
  }

  return <span> {trans[locale.code]} </span>
}
```

## useAuth

```tsx
'use client'
import { useAuth } from '@payloadcms/ui'
import type { User } from '../payload-types.ts'

const Greeting: React.FC = () => {
  // highlight-start
  const { user } = useAuth<User>()
  // highlight-end

  return <span>Hi, {user.email}!</span>
}
```

## useConfig

Used to retrieve the Payload [Client Config](../custom-components/overview#accessing-the-payload-config).

```tsx
'use client'
import { useConfig } from '@payloadcms/ui'

const MyComponent: React.FC = () => {
  // highlight-start
  const { config } = useConfig()
  // highlight-end

  return <span>{config.serverURL}</span>
}
```

If you need to retrieve a specific collection or global config by its slug, `getEntityConfig` is the most efficient way to do so:

```tsx
'use client'
import { useConfig } from '@payloadcms/ui'

const MyComponent: React.FC = () => {
  // highlight-start
  const { getEntityConfig } = useConfig()
  const mediaConfig = getEntityConfig({ collectionSlug: 'media'})
  // highlight-end

  return <span>The media collection has {mediaConfig.fields.length} fields.</span>
}
```

## useEditDepth

Sends back how many editing levels "deep" the current component is. Edit depth is relevant while adding new documents / editing documents in modal windows and other cases.

```tsx
'use client'
import { useEditDepth } from '@payloadcms/ui'

const MyComponent: React.FC = () => {
  // highlight-start
  const editDepth = useEditDepth()
  // highlight-end

  return <span>My component is {editDepth} levels deep</span>
}
```

## usePreferences

Returns methods to set and get user preferences. More info can be found [here](https://payloadcms.com/docs/admin/preferences).

## useTheme

```tsx
'use client'
import { useTheme } from '@payloadcms/ui'

const MyComponent: React.FC = () => {
  // highlight-start
  const { autoMode, setTheme, theme } = useTheme()
  // highlight-end

  return (
    <>
      <span>
        The current theme is {theme} and autoMode is {autoMode}
      </span>
      <button
        type="button"
        onClick={() => setTheme((prev) => (prev === 'light' ? 'dark' : 'light'))}
      >
        Toggle theme
      </button>
    </>
  )
}
```

## useTableColumns

Returns methods to manipulate table columns

```tsx
'use client'
import { useTableColumns } from '@payloadcms/ui'

const MyComponent: React.FC = () => {
  // highlight-start
  const { setActiveColumns } = useTableColumns()

  const resetColumns = () => {
    setActiveColumns(['id', 'createdAt', 'updatedAt'])
  }
  // highlight-end

  return (
    <button type="button" onClick={resetColumns}>
      Reset columns
    </button>
  )
}
```

## useDocumentEvents

The `useDocumentEvents` hook provides a way of subscribing to cross-document events, such as updates made to nested documents within a drawer. This hook will report document events that are outside the scope of the document currently being edited. This hook provides the following:

| Property               | Description                                                                                                                             |
| ---------------------- | --------------------------------------------------------------------------------------------------------------------------------------- |
| **`mostRecentUpdate`** | An object containing the most recently updated document. It contains the `entitySlug`, `id` (if collection), and `updatedAt` properties |
| **`reportUpdate`**     | A method used to report updates to documents. It accepts the same arguments as the `mostRecentUpdate` property.                         |

**Example:**

```tsx
'use client'
import { useDocumentEvents } from '@payloadcms/ui'

const ListenForUpdates: React.FC = () => {
  const { mostRecentUpdate } = useDocumentEvents()

  return <span>{JSON.stringify(mostRecentUpdate)}</span>
}
```

<Banner type="info">
  Right now the `useDocumentEvents` hook only tracks recently updated documents, but in the future
  it will track more document-related events as needed, such as document creation, deletion, etc.
</Banner>

## useStepNav

The `useStepNav` hook provides a way to change the step-nav breadcrumb links in the app header.

| Property         | Description                                                                       |
| ---------------- | --------------------------------------------------------------------------------- |
| **`setStepNav`** | A state setter function which sets the `stepNav` array.                           |
| **`stepNav`**    | A `StepNavItem` array where each `StepNavItem` has a label and optionally a url.  |

**Example:**

```tsx
'use client'
import { type StepNavItem, useStepNav } from '@payloadcms/ui'
import { useEffect } from 'react'

export const MySetStepNavComponent: React.FC<{
  nav: StepNavItem[]
}> = ({ nav }) => {
  const { setStepNav } = useStepNav()

  useEffect(() => {
    setStepNav(nav)
  }, [setStepNav, nav])

  return null
}
```

## usePayloadAPI

The `usePayloadAPI` hook is a useful tool for making REST API requests to your Payload instance and handling responses reactively. It allows you to fetch and interact with data while automatically updating when parameters change.

This hook returns an array with two elements:

1. An object containing the API response.
2. A set of methods to modify request parameters.

**Example:**

```tsx
'use client'
import { usePayloadAPI } from '@payloadcms/ui'

const MyComponent: React.FC = () => {
  // Fetch data from a collection item using its ID
  const [{ data, isError, isLoading }, { setParams }] = usePayloadAPI(
    '/api/posts/123',
    { initialParams: { depth: 1 } }
  )

  if (isLoading) return <p>Loading...</p>
  if (isError) return <p>Error occurred while fetching data.</p>

  return (
    <div>
      <h1>{data?.title}</h1>
      <button onClick={() => setParams({ cacheBust: Date.now() })}>
        Refresh Data
      </button>
    </div>
  )
}
```

**Arguments:**

| Property      | Description                                                                                     |
| ------------- | ----------------------------------------------------------------------------------------------- |
| **`url`**     | The API endpoint to fetch data from. Relative URLs will be prefixed with the Payload API route. |
| **`options`** | An object containing initial request parameters and initial state configuration.                |

The `options` argument accepts the following properties:

| Property            | Description                                                                                         |
| ------------------- | --------------------------------------------------------------------------------------------------- |
| **`initialData`**   | Uses this data instead of making an initial request. If not provided, the request runs immediately. |
| **`initialParams`** | Defines the initial parameters to use in the request. Defaults to an empty object `{}`.             |

**Returned Value:**

The first item in the returned array is an object containing the following properties:

| Property        | Description                                              |
| --------------- | -------------------------------------------------------- |
| **`data`**      | The API response data.                                   |
| **`isError`**   | A boolean indicating whether the request failed.         |
| **`isLoading`** | A boolean indicating whether the request is in progress. |

The second item is an object with the following methods:

| Property        | Description                                                 |
| --------------- | ----------------------------------------------------------- |
| **`setParams`** | Updates request parameters, triggering a refetch if needed. |

#### Updating Data

The `setParams` function can be used to update the request and trigger a refetch:

```tsx
setParams({ depth: 2 })
```

This is useful for scenarios where you need to trigger another fetch regardless of the `url` argument changing.

## useRouteTransition

Route transitions are useful in showing immediate visual feedback to the user when navigating between pages. This is especially useful on slow networks when navigating to data heavy or process intensive pages.

By default, any instances of `Link` from `@payloadcms/ui` will trigger route transitions dy default.

```tsx
import { Link } from '@payloadcms/ui'

const MyComponent = () => {
  return (
    <Link href="/somewhere">
      Go Somewhere

You can also trigger route transitions programmatically, such as when using `router.push` from `next/router`. To do this, wrap your function calls with the `startRouteTransition` method provided by the `useRouteTransition` hook.

```ts
'use client'
import React, { useCallback } from 'react'
import { useTransition } from '@payloadcms/ui'
import { useRouter } from 'next/navigation'

const MyComponent: React.FC = () => {
  const router = useRouter()
  const { startRouteTransition } = useRouteTransition()

  const redirectSomewhere = useCallback(() => {
    startRouteTransition(() => router.push('/somewhere'))
  }, [startRouteTransition, router])

  // ...
}
```
